Shuan Maling Tunnel Supporting Structure Mechanics Analysis And Collapse Measures Research

With the development of our infrastructure,a lot of tunnels were built quickly,Theaccidents of tunnel collapse often occurred. collapse accident threatens the property and safetyof the people. And invested the cost of governance is also increasing year by year.So it isnecessary to research the way to control measures.This paper based Shuang Ma Ling tunnel, through field investigation and monitoringmeasurement to obtain the accurate data. Set up a set of real reaction Shuan Ma Ling tunnelgeology physical parameters. Using Ansys software for supporting structure for numericalsimulation analysis.Comparing the measured data. Find out the problems in the theoretical.and discussed the cause of landslide and its treating method. Analyze the impact on thequality of tunnel lining thickness. Although select this geological condition of Shuan Ma Lingtunnel for the research. But the research for the design and construction of similar projectshas important guiding significance in future.Research work and achievements summarized asfollows:(1) The article research the types of collapse and failure mechanism of different collapsetypes.(2) According to the characters of the second lining of the tunnel structure, second liningmechanical calculation model is set up, though theory, analyzed the effects on the mechanicalbehavior of the tunnel lining thickness change.(3) Based Shuang Ma Ling project of the tunnel, The calculation model is set up accordingto the actual situation. The software of Ansys was used to numerically simulate thesupporting parameters.(4) Analyz the theory of Shuan Ma Ling landslide treatment and evaluate its effect.and findout the problems between numerical analysis and practical project. Analyzes the reason of theproblem to provide the reference for similar projects.
